Effects of interfacial interactions of solid microparticles on the emulsion containing ionic liquid

The present work deals with the effects of ionic liquid and solid microparticles on the properties of emulsions. We found that increasing the concentration of ionic liquid 1-butyl 3-methyl imidazolium hexafluorophosphate (BMIM-PF6) resulted into smaller mean droplet size of the dispersed phase. This effect of ionic liquid is more profound at comparatively low concentration of surfactant. Further, the addition of solid microparticles resulted in comparatively increased stability of the emulsions containing BMIM-PF6 which was the consequence of competitive interactions of solid microparticles and ions at the interfaces present in the emulsions.
